Why adb_install needs a policy

Installing APK files triggers execution of Android package installation on a device, which is an external operation with significant side effects — it introduces new software onto the device. This goes beyond a simple write, as it installs and registers executable code. Misuse could result in malicious app installation, making severity high.

POLICY

How to control adb_install

PolicyLayer is an MCP gateway — it sits between your AI agents and Android ADB MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for adb_install:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "adb_install": {
      "limits": [
        {
          "counter": "adb_install_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

adb_install stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Android ADB MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I block adb_install completely? +

Set action: deny in the PolicyLayer policy for adb_install. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides adb_install? +

adb_install is provided by the Android ADB MCP Server MCP server (landicefu/android-adb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Android ADB MCP Server tool call.

Start from Android ADB MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
